Johan co-organised and participated in Sage Days 75 on Algorithmic Coding Theory, taking place 22-26 August 2016 at Inria in Saclay, France. The workshop was attended by 35-40 SageMath enthusiasts, many of who made their first contributions to SageMath at the workshop.
The workshop served as the Grande Finale of the ACTIS project which Johan was part of. The project employed David Lucas as full-time software developer for two years for improving the Coding Theory support in SageMath.
